What this dot point is asking
NESA expects you to explain how Mao Zedong led the CCP to victory in the Civil War of 1946 to 1949. Strong answers integrate the Nationalist collapse (military, economic, political) with the CCP's strengths (land reform, the Manchurian base, Lin Biao's army) and the three decisive 1948 to 1949 campaigns.
The answer
From Sino-Japanese War to Civil War, 1945 to 1946
Japan surrendered on 15 August 1945. The CCP held about 95 million people in base areas behind enemy lines. The Soviet Red Army occupied Manchuria and turned captured Japanese stockpiles over to Lin Biao's forces from late 1945. The KMT, with US transport assistance, raced troops into northern cities.
The Chongqing Negotiations of August to October 1945 between Mao and Chiang Kai-shek produced the Double Tenth Agreement, a paper accommodation. The Political Consultative Conference of January 1946 collapsed.
The Marshall Mission, December 1945 to January 1947
US Special Envoy General George Marshall arrived on 20 December 1945 to mediate. A ceasefire was reached in January 1946. Marshall failed to secure a coalition; fighting resumed in Manchuria in April 1946 and full-scale war by July 1946. Marshall left China in January 1947 with the famous statement on a "dominant clique of reactionaries" in the KMT and "dyed-in-the-wool" Communists.
The strategic defensive, 1946 to 1947
In the early phase the Nationalists held the numerical advantage (about 4.3 million to 1.2 million). Chiang Kai-shek attacked Yan'an, which fell in March 1947; Mao evacuated and moved to Xibaipo. The Communists used mobile warfare and the strategic retreat, the doctrine of luring the enemy in deep. Peng Dehuai's Northwest Field Army in Shaanxi, Liu Bocheng and Deng Xiaoping's Central Plains Field Army in the Dabie Mountains, Chen Yi's East China Field Army, and Lin Biao's Northeast Field Army in Manchuria coordinated.
Lin Biao and the Manchurian base
Lin Biao's Northeast Field Army was the decisive force. By the start of the Liaoshen Campaign Lin commanded about 700,000 troops, with Japanese rifles, mortars and artillery from the Soviet handover and increasing US-supplied stocks captured from defeated Nationalist units.
The three decisive campaigns, September 1948 to January 1949
Liaoshen Campaign, 12 September to 2 November 1948. Lin Biao's forces took Jinzhou, Changchun, and Shenyang in Manchuria. The Nationalists lost about 470,000 troops. Manchuria was secured.
Huaihai Campaign, 6 November 1948 to 10 January 1949. The largest single battle of the war, in the plains between the Huai River and the Hai River north of the Yangtze. Chen Yi, Liu Bocheng, and Deng Xiaoping commanded against Du Yuming. The Nationalists lost about 555,000 men. The Yangtze line was effectively lost.
Pingjin Campaign, 29 November 1948 to 31 January 1949. Lin Biao moved south against Beijing (then Beiping) and Tianjin. Tianjin fell on 15 January 1949. General Fu Zuoyi surrendered Beijing peacefully on 31 January 1949. About 520,000 Nationalists were lost.
The three campaigns destroyed about 1.5 million Nationalist troops in five months. The KMT regime never recovered.
The crossing of the Yangtze and the collapse, April to October 1949
On 21 April 1949 the Communist forces crossed the Yangtze. Nanjing fell on 23 April; Shanghai on 27 May; Guangzhou on 14 October; Chongqing on 30 November. Chiang Kai-shek evacuated to Taiwan in December 1949 with about 1.2 million troops and civilians.
Land reform and CCP mobilisation
The Outline Land Law of 10 October 1947, drafted by Liu Shaoqi, replaced the moderate Yan'an rent-reduction policy with the confiscation of landlord and rich-peasant land for redistribution. By 1949 about 100 million peasants in CCP areas had received land. The campaign produced both a base of grateful smallholders and, in many villages, violent struggle sessions in which approximately 1 million landlords were killed by 1952 (the figure rose to about 2 million through the 1950 to 1952 nationwide land reform).
Nationalist collapse
Hyperinflation destroyed the urban middle class. The Shanghai cost-of-living index rose from 100 in 1937 to 1.93 million in 1946 to about 8.7 trillion by August 1948. The gold yuan reform of August 1948 collapsed within months. Corruption was systemic. The Generalissimo's son Chiang Ching-kuo's attempt to suppress speculation in Shanghai in 1948 collapsed against the Kong and Soong families. Conscript divisions deserted en masse, often with their American weapons, to the CCP.
Proclamation of the People's Republic, 1 October 1949
On 1 October 1949 at the Tiananmen rostrum in Beijing Mao Zedong proclaimed the establishment of the Central People's Government of the People's Republic of China. About 300,000 people attended the ceremony. The Common Program adopted on 29 September 1949 served as a provisional constitution.

Historiography
Lloyd Eastman (The Abortive Revolution, 1974, Seeds of Destruction, 1984) emphasised the structural failure of the KMT regime: corruption, hyperinflation, the disconnect between the regime and the peasantry.
Suzanne Pepper (Civil War in China, 1978) emphasised CCP organisational superiority and the appeal of land reform.
Odd Arne Westad (Decisive Encounters, 2003) gave the standard post-Cold War synthesis with archival access from both sides.
Maurice Meisner treats the victory as a peasant revolution legitimated by Japanese-war patriotism rather than as a Soviet-style proletarian seizure.
Jung Chang and Jon Halliday (2005) argued Stalin orchestrated the victory and that Mao's role was overstated; the case is rejected by most specialists.
Common exam traps
Reducing the victory to land reform. The 1948 to 1949 campaigns were industrial-scale conventional warfare; land reform supplied the recruits.
Forgetting Soviet aid in Manchuria. The Soviet handover of Japanese stockpiles to Lin Biao in 1945 to 1946 was decisive.
Treating Chiang as a competent commander. Most specialists treat his personal interference as a major cause of Nationalist defeat.
In one sentence
Mao Zedong's victory in the Chinese Civil War of 1946 to 1949 rested on the Manchurian base armed by the Soviet handover and Lin Biao's Northeast Field Army, the Outline Land Law of 10 October 1947 that mobilised approximately 100 million peasants, and the three decisive campaigns of late 1948 to early 1949 (Liaoshen, Huaihai, Pingjin) that destroyed about 1.5 million Nationalist troops, against a KMT regime undone by hyperinflation, corruption, and Chiang Kai-shek's strategic micromanagement, culminating in the proclamation of the People's Republic at Tiananmen on 1 October 1949.

A 10-mark "account for" needs causes, not narrative.
Nationalist weakness. The KMT emerged from the Japanese war with about 4.3 million troops on paper, hyperinflation (the price index in Shanghai rose from 100 in 1937 to about 8.7 trillion in 1949), endemic corruption, and a war-weary urban population. Chiang Kai-shek's tendency to micromanage divisions from Nanjing crippled field operations.
CCP strength. Mao led a 1.2 million-member party and an army of about 900,000 regulars at war's end. The Soviet occupation of Manchuria (August 1945 to May 1946) delivered captured Japanese weapons to Lin Biao's forces.
The Marshall Mission, December 1945 to January 1947. General George Marshall failed to broker a coalition. The truce collapsed in mid-1946.
Strategic phase, 1946 to 1947. Chiang took Yan'an in March 1947 but the CCP retreated in good order. Peng Dehuai's Northwest Field Army harassed.
Lin Biao in Manchuria. Lin Biao's Northeast Field Army, equipped with Japanese weapons, defeated the Nationalists at the Liaoshen Campaign (September to November 1948), securing Manchuria with about 470,000 Nationalist casualties.
Huaihai Campaign, November 1948 to January 1949. The decisive campaign north of the Yangtze. About 555,000 Nationalists killed or captured.
Pingjin Campaign, November 1948 to January 1949. Beijing fell on 31 January 1949 when General Fu Zuoyi surrendered.
Land reform. The Outline Land Law of 10 October 1947 redistributed land in CCP-held areas. About 100 million peasants received land. The CCP recruited from this base.
Proclamation. Mao proclaimed the People's Republic at Tiananmen on 1 October 1949.
Markers reward Liaoshen, Huaihai, Pingjin, Outline Land Law, and the strategic comparison of CCP and KMT.
